Restore reliable high-voltage insulation between the ignition coil and spark plug with the ThunderCore PRO Coil Boot 900-P2052 (also written 900P2052). This OE-replacement boot fits the 1999-2001 Chevrolet Metro, 1999-2004 Chevrolet Tracker, 1999-2000 Pontiac Firefly, 2002-2007 Suzuki Aerio, 2000-2002 Suzuki Esteem, 1999-2005 Suzuki Grand Vitara, 1999-2001 Suzuki Swift, 1999-2004 Suzuki Vitara, and 2002-2006 Suzuki XL-7 — see the "Vehicles it fits" section for engine-specific coverage.
In coil-on-plug (COP) and coil-near-plug (CNP) systems, the coil boot forms the insulative path between the coil and the spark plug. Over time, heat, vibration, and chemical exposure can degrade a boot, leading to arc-through, misfires, or hard starting; if a worn or cracked boot is the cause, this part replaces it.
- OE-Replacement Quality: engineered to match OE dielectric strength, boot length, and connector geometry.
- Restores Ignition Insulation: replaces worn or cracked boots to help maintain proper spark isolation and reduce voltage loss.
- Heat & Chemical Resistant: constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.

Frequently Asked Questions
What does this coil boot do?
In coil-on-plug and coil-near-plug systems, it forms the insulative path between the ignition coil and the spark plug, providing high-voltage insulation and secure coil-to-plug contact.
What are signs a coil boot may need replacing?
Boots can degrade from heat, vibration, or chemical exposure, which may show up as arc-through, misfires, or hard starting. Diagnose the cause first, since misfires can have other sources.
Which vehicles does the 900-P2052 fit?
It's listed for the Chevrolet Metro and Tracker, Pontiac Firefly, and Suzuki Aerio, Esteem, Grand Vitara, Swift, Vitara, and XL-7 across model years 1999-2007. See the "Vehicles it fits" section for the full list.
What is this coil boot made from?
Per the manufacturer, it's constructed from high-temp silicone and reinforced materials to resist oil, fuel, and under-hood heat.
Is this an OE-replacement part?
Yes. The manufacturer states it's engineered to match OE dielectric strength, boot length, and connector geometry for consistent performance.
